The short answer
Deerfield has a median build year of 1974 across its housing. That is late enough for copper and early enough for polybutylene in places, which is why the pattern of the symptom is worth establishing before anybody is called out.

What 1974 tells you about the pipe in Deerfield
Housing of this vintage generally means copper as the usual supply material, so corrosion narrowing the pipe is far less likely. In houses of this era a whole-house pressure drop points at the pressure-reducing valve, the main shut-off, or the supply side of the meter rather than at the pipe itself. More on 1970s supply pipe.
85% of occupied homes in Deerfield are owner-occupied, 21 points above the IL figure of 64%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

In Deerfield, count the weak taps before you do anything else. Every one of them points at the supply; a single one points at that fixture, and the difference decides whether this costs you five minutes or a contractor. Normal supply is 45–80 psi and under 40 psi is low (here is the test). Then: whole house or one tap.
